Description

All File system APIs (provided by cordova-plugin-file) appear to be missing in web workers. Oddly I can make XMLHttpRequests of the filesystem with file urls in workers.

In the main view running the following suggests there is no access to the filesystem directly:

var blob = new Blob(["onmessage = function(e) { var res, fn, msg; try{ fn = new Function(e.data); res = fn(); msg = JSON.stringify(res); }catch(err){ msg = JSON.stringify(err); }; postMessage(msg+' <> '+fn); }"]);
var blobURL = window.URL.createObjectURL(blob);
var worker = new Worker(blobURL);
worker.onmessage = function(e) {
  console.log('worker',e)
};
worker.postMessage('return 1+1');
worker.postMessage('return self.File');
worker.postMessage('return self.requestFileSystem');
